A sharp-eyed New Orleans Police officer making a seemingly routine traffic stop Sunday night wound up arresting a suspect wanted for incidents of carjacking, assault and domestic battery.

Jamair Guy, a 20-year-old New Orleans man wanted for more than seven months, was the passenger in a Chevrolet Tahoe that was pulled over shortly before 8 p.m. Sunday near the intersection of North Robertson and Spain streets in the St. Roch neighborhood. NOPD 5th District officer Lawrence Weathersby Jr. stopped the vehicle because of its malfunctioning tail lights, according to a police report.

Guy and driver Curtis Murray, 29, were asked to step out of the vehicle because of a strong aroma of marijuana wafting from inside. Police said a search of the SUV turned up a container of marijuana and a .45-caliber handgun hidden inside a cup holder console. Both men replied, "That's not mine," according to the arrest report.

Both men were arrested on charges of possessing marijuana and an illegal firearm. Guy faces an additional charge of firearm possession by a convicted felon.

Shortly afterward, a records check found that Guy was wanted on outstanding warrants in connection with second-degree battery for attacking his pregnant ex-girlfriend in June 2013, and for a violent carjacking incident last September in eastern New Orleans.

Court documents show Guy had been wanted for second-degree battery since June 5 for pulling the hair and arm of a pregnant woman who had broken off their relationship three days earlier. The woman suffered a deep cut to her left hand that required 12 stitches after she clung to a fence as Guy pulled her from behind, according to the arrest warrant.

Last September, Guy was identified in a photo lineup as one of two men who used a handgun to steal a Ford F-150 pickup truck in eastern New Orleans from a man who had agreed to have drinks with them. In that incident, the victim told police he was acquainted with the assailants, but was shocked when Guy pulled a gun on him after he drove them to the 3000 block of Oliver White Street as they requested.

According to the police report on that incident, Guy told the victim, "You know what time it is," before striking him on the head with a silver pistol. The victim said he was ordered to run away, but turned to see Guy climbing behind the wheel of the truck and driving off with his accomplice, later identified as Terell Hathorn of New Orleans.

Guy, who also is known by the nickname "Mya," was charged with carjacking, aggravated assault, aggravated battery and illegal possession of stolen things in connection with that case.
